On the first point, the answer is prompt. Emphatically, the mediæval world was worth preserving. In fact, with Periclean Greece, the Empire under the Antonines, and possibly the world of the Victorian age, the thirteenth century marks one of the culminating points of human history. It is true that the word “mediæval” is still popularly used in derision. But, on the other hand, such usage is recognized as hasty and superficial by virtually all educated men acquainted with the period. The Middle Ages attract us by the excellence of their arts and handicrafts, by the vividness and picturesqueness of their life, their spontaneity of feeling, their absence of hypocrisy, the order and clarity of their intellectual life, above all by their freedom from serious internal strain. From our world of alternatively drab and garish machine-made ugliness, haphazard and inconsequent thinking, and torment of chronic industrial civil war, we look back upon them with regret. In the literature of the thirteenth century we see the European mind happy and creative ... as it is to-day uncertain and near despair. We see our typical institutions, such as representative government, sounder and more vigorous than they are to-day. Such eager worshippers of the spirit of our own time as H. G. Wells and Henry Adams, to name only two at random, bear their testimony. The confession of the volatile socialist Wells is interesting. In 1914 he casually wrote of “... the finished and enriched normal social life of Western European in the Middle Ages....” I have taken Wells as important merely because (with his human sensitive-plate of a mind capable of so many discordant impressions) he puts the thing so neatly. With such men as Chesterton and Belloc in England and Cram in America the appreciation of mediævalism is the very core of their thinking. It would be easy to weary the reader with examples. The Middle Ages draw us if we but look at them. The weakness of the Middle Ages lay in four things. First, there was insufficient organization of public powers and of communications, a subject discussed elsewhere in this book. Second, there was very little “natural science,” i.e., detailed knowledge of the properties of the material world. Thus it was ignorance of medicine and sanitation that brought about the great fourteenth century calamity of pestilence, the “Black Death” which gave the mediæval system a shock from which it never fully recovered. Third, there was cruelty, and fourth, there was the contrast between the vast assumptions made by the Church and the shortcomings and weaknesses of man himself—layman and churchman alike. Both cruelty and the claims of the Church are intimately connected with our subject.
